ADJUSTABLE WRENCH.

' SPECIFICATION forming part of Letters Patent No. 593,354, datedNovember 9, 1897.

Application filed July 3, 189.7. Serial No. 643,398. .0510 model.)

T0 at whom it may concern:

Be it known that I, MARK M. FUNK, of Mercersburg, in the county ofFranklin and State of Pennsylvania, haveinvented certain new and usefulImprovements in Adjustable Wrenches; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to an improved adjustable combination nut andpipe wrench, and has for its object to provide a simple device of thischaracter by which either nuts or pipes may be rotated and which may-bead- I justed with the greatest expedition, so as to engage with any sizepipe or nut within the limits of its capacity.

In the drawings herewith forming part of this specification, Figure 1 isa perspective view of my improved adjustable pipe and nut wrench. Fig. 2is a side elevation. Fig. 3 is an edge view thereof.

In the construction of my improved combination pipe and nut wrench Iprovide, first, a straight bar or shank portion 1, having secured uponor formed integrally therewith at one end a fixed jaw 2, the said shankportion meeting said jaw approximately of its vertical center. One ofthe inner surfaces 3 of said jaw 2 is cut so as to form a right anglewith the shank 1. The other face 3 of said fixed jaw is outwardlyinclined at a point upon the lateral surface of the shank 1. Near itslongitudinal center I provide a plurality of ratchet-teeth 4, saidratchet-teeth being inclined forwardly toward the wrench-head. I nextprovide a sliding jaw 5, which consists of a portion substantiallysimilar to the fixed jaw and provided in its vertical center with arectangular aperture adapted for the passage of the shank portion 1. Oneof the meeting faces of said sliding jaw 5 forms a right angle with theshank 1 and the other portion is inclined backwardly and provided with aseries of ratchet-teeth 7, the said ratchetteeth being inclined towardthe outer fixed jaw 2. I next provide, extending backwardly from saidsliding jaw 5 in line with said shank portion 1, a lateral spring-plate8, formed integrally with said jaw and provided at its free end with adownwardly-projected pawl 9, adaptedtobe engaged successively by theratchet-teeth-4. The said plate 8 is adjacent .to the pawl portion 9,provided with two extended portions 10 10 for lifting said springplateand thereby disengaging said pawl 9 from engagement with saidratchet-teeth 4. By means of the construction hereinbefore set forth thewrench may be incidentally adj usted to either a nut or pipe by eitherdrawing backwardly or moving forwardly the said sliding jaw 5, and afteradjustment the said sliding jaw will be held firmly in engagement withthe nut or pipe by means of the pawl 9 one end of said shank portion, asliding jaw mounted upon the shank portion, ratchet-.

teeth formed upon one of the inner surfaces of said sliding jaw,ratchet-teeth formed upon one of the lateral surfaces of the shankportion, a spring-plate extended rearwardly from said sliding jaw, apawl formed at the end of said spring-plate adapted to be engaged by theratchet-teeth upon said shank portion, and laterally-projected portionsformed upon said spring-plate adjacent to the end thereof for liftingsaid pawl out of engagement with said ratchet-teeth. v

2. The combination in an adjustable pipe and nut wrench, of a shankportion, a fixed jaw upon the end-thereof, one end of said jaw forming aright angle with the shank portion, and the other portion of the jawinclined outwardly, ratchet-teeth formed upon the lateral surface ofsaid shank, a sliding jaw provided with an aperture adapted to receivesaid shank, ratchet-teeth formed upon one of the rearwardly-inclinedsurfaces of the of said spring-plate adapted to engage with theratchet-teeth formed upon said shank, and laterally-projected portionsformed upon said spring-plate for lifting said pawl out of engagementwith said ratchet-teeth.

3. An improved combination pipe and nut Wrench, consisting of a shank, afixed jaw upon one endiof said shank, ratchet-teeth for lifting saidpawl out of engagement with said ratchet-teeth, and other ratchet-teethformedupon one of the inclined inner sur faces of the sliding jaw soasto form in conjunction with the oppositely-i'nclined surfaces of thefixed jaw a pipe-wrench, the other opposite meeting surfaces of thefixed and slid ing jaw forming a nut-wrench, the whole constructed,arranged and adapted for operation, substantially as and for the purposeherein set forth.

In'testimony whereof I have signed this specification in the presence oftwo subserib ing witnesses.
